Meta-search tool with clustering, indexing, and automatic relevance updates

SearchAlyzer2 simultaneously queries the common search engines and then clusters, indexes, and sorts those search results. Clusters are groups of related search results. The index is automatically built from the search results. In addition, marking interesting search results or index words finds related results or words, as measured by updated relevance bars. Unlike other search tools, marking an index word of interest automatically updates the relevance of all pages to that word. The pages of interest can be found without having to scan through the entire list of pages. Marking an interesting page also updates the relevance of all pages to the marked page. You can automatically adjust the number of chapters created for either a broad overview of results, or a detailed view of page clusters. The number of index words can also be adjusted, from the most common words to all words, even those appearing in only one page. Finally the number of results to get can be adjusted from 50 up to 1000 total results. SearchAlyzer2 also removes duplicate results (but still lets you see them), lets you choose which engines to search on and how long to wait for their results, lets you control the length of phrases in the index, lets you control which words should be ignored in the index (the stop words), and more. Finally, SearchAlyzer2 can evaluate the power of each engine it uses by measuring each engine s coverage, relevance, and independence.
